People also ask
What is the purpose of a varistor?
Varistors are used
to protect a circuit from high voltage surges
. When a high voltage surge is applied to a circuit, the outcome is usually catastrophic to the circuit. A capacitor may be installed across the signal lines.

Where would you use a varistor?
Block varistors and strap varistors are high-energy type products used for
power supplies of industrial devices and communication devices, power switchboards at power plants and power substations, railway signal systems, and others
, and their advantage is an extremely high surge current capability.

What happens when a varistor fails?
Varistors that have failed
no longer provide protection against over-voltages
. However, it is typical for them to fail to a short-circuit condition, causing a local fuse such as the one in the image provided to open, indicating a fault of some kind.

What is the difference between a varistor and a SPD?
Varistors, also known as voltage-dependent resistors, are used as part of surge protective devices (SPDs)
. Varistors are designed to provide protection against transient overvoltages by limiting the voltage across the device to a safe level.

A varistor is a resistive device with non-linear voltammetric characteristics,
mainly used for voltage clamping
when a circuit is subjected to overvoltage.
